I did the update from AT&T this morning on my daughter's unrooted stock phone and now MotoBlur/Desktop won't load and I can't get into settings or anything. Proceed with caution. I see a blank screen with the top pull down bar with AT&T on the left, Wifi, 3G Bars, Battery and Clock that's it. I tried removing the battery and Sim and reinstalled them with no luck. Looks like I'll need to make a trip to the AT&T store.
